As you can see, the Nook Cream has just the white trimwork to separate it from the regular Nook Touch. There's really nothing to recommend it other than the fact it is pretty.
I want one.
I'm going to post the video, but I wouldn't watch it. The guy wastes the first 50 seconds blathering before he opens the box and lets us see the Nook Cream. It's incredibly irritating. But if you do watch it, skip the first 50 seconds.
If you can still find one of these ereaders, I'd go for it. It's pretty. But it is also quite limited in supply, so good luck.
